Density = Mass / Vol
What you pay is for the Vol (in litres)...When the density is high you get more mass of the chemical components in a lit of volume which otherwise is lesser during hotter temperature...
More molecules per lit means more combustion for a lit of fuel and hence more FE...
Hope that clears your point....
